Sundowning behavior, also known as sundown syndrome or late-day confusion, refers to a pattern of behavioral changes that some individuals with Alzheimer’s disease or other forms of dementia experience in the late afternoon or early evening.

During sundowning, the person may become more agitated, confused, disoriented, or anxious. They may also experience mood swings, restlessness, pacing, or wandering. The symptoms tend to worsen as the evening progresses and can continue into the night, making it difficult for the person to sleep.

The exact cause of sundowning behavior is unclear, but it may be related to changes in the person’s internal body clock, fatigue, sensory overload, or the effects of medication. Environmental factors such as low lighting, shadows, or unfamiliar surroundings can also contribute to sundowning.

Managing sundowning behavior can involve:

  • Creating a calming and consistent routine.
  • Providing structured activities during the day.
  • Avoiding caffeine and alcohol in the evening.
  • Minimizing environmental triggers.
  • Using medication or other therapies as prescribed by a healthcare professional.

At What Stage of Dementia Does Sundowning Occur?

Sundowning behavior is typically associated with the middle to late stages of dementia, although it can occur in any stage. It is more commonly seen in individuals with Alzheimer’s disease but can also occur in people with other forms of dementia.

Sundowning develops gradually as the disease progresses, with symptoms becoming more frequent and severe over time. It can be one of the most challenging behaviors for caregivers to manage, as it can be unpredictable and disruptive to the person’s daily routine.

Not all individuals with dementia experience sundowning behavior, and those who do may exhibit different symptoms and patterns. If you or a loved one is experiencing symptoms of sundowning or any other behavior changes, it’s essential to consult with a healthcare professional for guidance and support.

What Are the Early Signs of Sundowning?

Sundowning behavior can manifest differently in different individuals, but here are some early signs that may indicate the onset of sundowning:

  • Increased confusion or disorientation in the late afternoon or early evening.
  • Mood swings or irritability appear to be triggered by changes in lighting or shadows.
  • Difficulty sleeping or staying asleep at night.
  • Restlessness or agitation, such as pacing or wandering.
  • Increased sensitivity to noise, light, or other sensory stimuli.
  • Changes in appetite or eating habits.
  • Fatigue or lethargy during the day may contribute to increased agitation in the evening.

Suppose you or a loved one is experiencing any of these symptoms. In that case, it’s essential to talk to a healthcare professional to determine if sundowning or another underlying condition is the cause. Early intervention and management can help minimize sundowning’s impact on daily life and improve the quality of life for the person with dementia and their caregiver.
